y Speciiicaton forming part of Letters Patent No. 104,614, dated June 21,' 1870.

To all whom it may concern:

Be it known that I, WILLIAM S. MASON, of the city of Raleigh, in the county of Wake,

' `in the State of North Carolina, have invented a newand improved Mode of Cooling by the Condensation of Atmospheric Air; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the letters marked thereon.

The nature of the invention consists in the peculiar construction 1of a receiver for holding and abstracting the heat from condensed at' mospheric air, andI in the regulator for controlling theuse of condensed air for cooling purposes. The receiver is *a cylinder of, say, from ten to fifteen feet in length, and from four to six feet in diameter, and is made of sheet copper or other metal, sufficiently thick to resist the elastic force of any number of volumes of atmospheric air that it may be determined to condense into one. For the purpose of carrying off the excess of heat evolved during the process of condensation, the cylinder is fitted with' a large number of lues, B', of any required shape, say of two inches in diameter, `extending from end to end,leaving a space in the cylinder above and below not occupied by lues, as shown by a cross-section of the cylinder. (See Fig. 2, letters A and D.)

Cold Water is made to flow through these lues to carry olf the evolved heat, the cylinder being constructed with boxes, I and L, (see Fig. 1,) for the reception and discharge of the Water. `The box I has an icebox, K, for still further reducing the temperature of .the water before passing through the ilues, in case a more speedy reduction of heat is required, and a stop-cock, M, to let off the Water at will afterward. B B are check-valves through which the air, after being condensed by theIair-purnps G C, passes into the receiver from below, (see Fig. 1,) and so up and around the lues to the space A, Fig. 2. E E, Fig. 1,

are two force-pumps for the purpose of injecting through the tubes F F a stream of cold Water into the chambers of the air'pumps C C at the moment of condensation; and M is a stop-cock to let oft' any water that may accumulate in the cylinder. At N is attached an air-gage, to indicate the degree of condensation; and O is a pipe for conducting the condensed air to any required locality.

The regulator consists of aV metallic rod, U, Fig. 1, one end being attached to some fixed point and the other to a metal lever, T, at a point, V2, near a point, V, which is also a xed point. lFrom the other end of the bar T an adjustable bar, S, extends to one end of a lever, Q, the other end of said lever being attached to a valve, yl?. The spiral spring lt is used to avoid the error occasioned by looseness of joints. The expansion and contrae-| tion of the bar U will operate to open and shut the valve upon each Wing of which thepressure from within is equally balanced on each side of its center .or pivot, the quantity of air to be allowed to pass being regulated by the bar S. The oar U Inay be of any required length,I and be made of brass or of any other metal, or it may be constructed of two bars, one of metal and the other of another metal, of Wood, or of glass. When two bars are used, the upper end of one is attached to the point V2, and of the other to the point V of the bar T. The bar T and the lever Q lare to be made of sufficient length, according to circumstances, to cause a valve, P, to open and shut,`upon the expansion and contraction of the bar U, to permit the desired escape of condensed air. Instead of the bar U, a glass tube, W, (Fig. 3,) with a bulb'7 Y, at the lower end, to be filled with mercury, may be used. A wooden float, at X,resting on the column of mercury, is to be attached to the lower end of the rod Z, the upper end of which is attached to the point V2, Fig. 1. The expansion and contraction of the mereurial column answering the purpose of the bar U, in Fig. 1, will Inove the valve in the same manner 5 or, two bars of di'erent metal of different expansive powerfeither soldered or riveted together, may be used, (see Fig. 4;) or, the bar` U, Fig. l, may be made to operate at the point V, the ends of T and U being adapted to each other, and the xed point `or fulcrum being at V2. R. may be adjusted above or below, according to circumstances.
